The Ten-Tec ORION represents the most innovative HF transceiver ever created for amateur radio use. Our aim in designing and producing this radio was to meet the demands of increasingly intense competition in DX and contesting, while adding many nonperformance related features that the active ham can also appreciate. The features and performance ORION brings to ham radio will enhance HF radio contacts of all sorts, while opening new possibilities for amateur radio operation. ORION offers world-class reception and transmission of CW, SSB, digital modes, FM, and AM on all 10 HF amateur bands, plus excellent general coverage reception via the second (sub) receiver from 100 kHz to 30 MHz.
